JLNims -> Misbehaving G String (Jun. 10 2022 7:52:24)

A question for the luthiers: I have noticed some tuning issues with my G string. When I strobe tune all strings open they play and sound in tune for ~15 minutes. After that time , I check an open chord, say E major, and the G string is off a bit. Going back to the strobe tuner, the G is slightly sharp while all other strings remain in tune. That's the first part of my question, how can that be? The second part of my question is if I open strobe the G string, and play the G string at whole notes up the fret board, the pitch grows slightly sharper the way up. At the 12th fret, it is sharp by 2 or 3 cents. But the harmonic at the 12th fret is correct. But only the G string does this. Am I missing some sort of adjustment that was never done during initial setup? Personally, I have done nothing in the form of setup to this guitar, other than just changing strings; and cleaning the fretboard and frets with a dry clean soft cloth (no chemicals or soaps used). Also while the strings are off during changing (I usually replace each string at a time, leaving the others tensioned, never all at once), I will clean the nut grooves with a wood toothpick IF it looks a bit dirty. If it weren't for the strobe accuracy, and my ears, I would think voy loco en mi cabeza! Bad G string!! What say any of you? -Jeff
